Any guess, or bet, on what might be the cause of a very recent startup problem that only seems to happen when starting up the Saturn for the first time of the day only? Weird, it starts like a rocket any other later time after that initial first-of-day startup. The battery voltage is 12v in the morning prior to startup. After I do manage to get it going, the voltage is almost 15 volts from the charging of the alternator. When I try to get it going initially, I turn the key on and nothing but dash lights. Turn key, off and on, a couple of times and then it starts up and runs beautifully. The rest of the day it starts right up at the first turn of the key. The starter is quite new and is a reman unit which has run great. Cleaned cables everywhere when putting in the new starter. From what threads I've perused, sensors seem to be a likely candidate. Fuel filter is fairly new, with approximately 10k miles on it. New wires, plugs, no oil leaks, clean EGR with new gasket. I do have to short out the contacts to get the dash error codes. Just haven't done that yet. Oh, the battery is fairly new also. It was replaced less than a year ago. Do ETCS's go bad after a few years or so? Just wondering, or how about CPS? I will reread my Chilton book, but it seemed, if I recall correctly, that there weren't any codes for these sensors when they get to be borderline. Anyone with deep experience and has advice to give here with my slight problem with my Saturn will be appreciated. I don't have much green left to just throw parts into it and certainly do not wish to visit the labor expensive auto repair dudes as I just don't have anything to spare anymore. Thanks, I hope..........
